Spring hinge



May 30, 1933. P. J. MARCH SPRING HINGE Filed May 25, 1932 I." Marcia; BYwzj /mmw ATTORN EY Patented May 30, 1933 PETER J. MARCH, or the vn'eAs;:JiTEYADA' V 3 SPRING HINGE Application filed May 25,

the provision of a hinge, wherein the spring for the same is mounted ina novel manner so that such spring can be adjusted to tension the leavesof the hinge or the said spring uncoupled so that the hinge will bedevoid of spring action in the use thereof, the manner of adjustment ofthe spring being novel in form and is manually regulated.

Another object of the invention is the provision of a hinge of thischaracter, wherein the spring in association therewith is concealed andis regulated by an adapter so that the spring can be utilized for thepurpose of having the hinge function as a door closer.

A further object of the invention is the provision of a hinge of thischaracter, wherein the same is mountable in different ways between astationary and swinging part and will permit the swinging of suchswinging part either under tension or without such tension, the hinge inits entirety being of novel construction.

A still further object of the invention is the provision of a hinge ofthis character which is extremely simple in construction, thoroughlyreliable and eificient in its purble. and inexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinvention, and pointed out in the claims hereunto appended.

In the accompanying drawing 2- V Figure l is an elevation of a hingeconstructed in accordance with the invention, the spring barrel being insection.

Figure 5 is a sectional viewon the line55 of Figure 1 looking inthedirection of the a w Figure 6 is a detail plan view of an adjunct.imilar reference characters indicate corresponding :parts throughout theseveral views in the drawing.

Referring to the drawingin detail, the spring h nge comprises a pair ofleaf plates .10 and 11 respectively, these provided with fastener holes12 to accommodate screws or other'fasteners for the securing ofsaidplates upon a. stationary andswinging part. i 5

.The'plates 10 and llintermediate thereof are provided with matchedcut-out portions 13, while the plate 10 isformed with the upper and.lower pintle eyesll and 15 respectively and the plate ll is' formed with9 a pair of spaced upper pintlei eyes 16 and a lower .pintle eye 17respectively. Engaged .w th the upper pintle eyes 14 and l6 is a pintlel8 constituting the spring adjuster having an outer head 19 carrying afinger hold or'wing 20 and likewise engaged in the pintle eyes 15 and 17is a pintle 2 l,,the same formed .with an inner squared head 22, whilethe outer end is threaded at to accommodate a terminal nut 24. Y -8pose, possessing but few parts, strong, dura- The squaredinner end 22.of the pintle 21 isfitted in a correspondingly shaped center opening'in a cone 25. about which is welded the outer coil of a convolutedtensioning spring 26, the other end of which fits and is welded on acone .27 threaded-on the inner .end of the pintle 18, the spring beinglocated between said cones.

.. Surrounding the spring 26 is a barrel 28 which confines the springand also receives-9 in opposite ends thereof the cones 25 and 27, thisbarrel 28 being located within the cutout portions 13. in the plates 10and 11. i

, The cone 27 is-formed with ratchet teeth co-acting withyratchet' teeth30 on the?- lowermostpintle eye, 16, andin this fashion v a latchingcoupling is had therebetween.

The'pintlefeye 15 next to the cone 25 is formed with a squared socket 31for the squared end 22 of the pintle 21 so that when the cone 27 islatched with the eye 16 the leaf plates 10 and 11 will be tensioned bythe spring 26. On adjustment of the pintle 18 in a manner to move thecone 27 out of engagement with the pintle eyes 16 the spring 26 willuntension the plates and 11 and the hinge will function as the ordinarynonspring hinge. When the spring 26 is coupled by the cone 7 i 10 27with the pintle eyes 16 the hinge will funca tion as a door orother'swingingpart closerr It should be apparent that in the use-of thehinge structure hereinbefore described the necessity for the employmentof friction casement adjusters or other similar adjusters for eithercasement windows, doors or the "like will be avoided. V I z Whatis-claimed is i l 1. A hinge of the character described oom'- :26prising leaf plates, pintles pivotally connect' 1 l ing the'platestogether and spaced apart, one pintle being fixed with one plate, clutchmeans adj ustably connected with the other pintle and engageable withthe other plate, acoiled tensioning spring acted upon by said last namedmeans to render A the :same .active or inactive, and a barrelsurrounding-the spring. r a 2. Ahinge of the characterdesc'ribedcomprising leaf plates, pintles pivot-ally connecting theplates together and spaced apart, one pintle bein fixed with one late,clutch means ad'ustably connected the other pintle and engageable withthe other plate, acoiled tensioning spring acted upon by said last namedmeans to renderthe sameactive or inactive, a barrel surrounding thespring, and means for adj usting the pintle'connected with 'saidfirst"named means to render the spring active or inactive. l

3. hinge of the haracter described, a pair of leaf plates, pintle "eyesformed on said plates, pintles engaged in 'said'eyes forswingingly-connecting the plates,m'eans=on 43 one pintle to make thesame fast with one plate, means on the other pintleto make the same fastwith the other plate, means for releasing said last named means, and-acoiled spring connected with the first "and last named means.

'4. In 'a hinge of the character described, a pair of leaf plates,pintleeyes formed on said plates, pintles engaged in :said eyes forswingingly connecting the plates, means on '0ne pintle to make the samefast withione plate, :means on the other pintle to make the same'ifastwith the other plate, means'for releasing said last named means, acoiled sprin connected with the "first and last '60 name means, and 'abarrel encasing the spring and held be'tween said pintle eyes;Intestimony whereof I affix my signature.
